players can use electric Wrench to ignore permission(essentials-groupmanager) and open other's double chests or change their direction.
they can do this without permission so that players can use electric Wrench to stolen other's things.
this is a very serious bug in my server （version:1.12.2）
i like ic2 and i hope this bug will be fixed as soon as possible.
thanks
